How come saltwater crocodiles don't inhabit the salty reef, you ask? It's a good question – but the Great Barrier Reef's clear water, lack of crocodile-friendly food sources and large swimming distances from the mainland make seeing a crocodile on the outer reef (aka where the reef tours go) extremely unlikely.
Snorkeling is an extremely safe activity, especially if you take all of the correct precautions and listen to your own body whilst swimming. Below are some basic Great Barrier Reef snorkeling safety tips. Fitness. Make sure you only snorkel / swim to your fitness levels.
They are both fearful and fascinating creatures, with the Saltwater Crocodiles known for being the largest living reptile on earth. They are found throughout Australia's northern region, and Cairns is no exception.
Crocodiles. Crocodiles are not normally found on the Ningaloo Coast, but there have been rare and isolated occurences of estuarine or saltwater (saltie) crocodiles in the area.
You can gradually reach the reef and choose a depth you're comfortable with. If you are snorkelling from the beach, heading out one hour before high tide offers better visibility and gives you enough time to snorkel before the currents change.
Natural Territory: In Australia's outback, the saltwater crocodiles are found in the salty water along the coastline. But they are not limited to only the backcountry and can be found in the billabongs, freshwater rivers, and swamps.
But how quickly can they run? Most crocodiles can achieve speeds of around 12 to 14 kph for short periods, which is somewhat slower than a fit human can run. Don't believe the hype - if you're reasonably fit, you can definitely outrun a crocodile!
This off-the-scale opportunity to swim with two saltwater crocodiles is the only one of its kind in Queensland and allows park visitors to swim eye-to-teeth with these terrifying apex predators and live to tell the tale! CrocArena is home to the spine-tingling Swim With The Salties experience.
The most common species of sharks seen on the Great Barrier Reef are white tip or black tip reef sharks. These sharks feed on fish and pose no danger to humans, in fact they are timid and are easily scared.
Species of Sharks on the Great Barrier Reef
First let us say this, there are no Great White Sharks on the Great Barrier Reef. The water is far too warm for them.
The short answer to this? Absolutely! Despite being submerged in the deep ocean water, you don't have to be a swimmer to see the underwater wonderland that is the Great Barrier Reef.
Estuarine crocodiles mostly occur in tidal rivers, coastal floodplains and channels, billabongs and swamps up to 150 km inland from the coast. The estuarine crocodile usually inhabits the lower reaches of rivers, while the upper reaches are inhabited by the freshwater crocodile (Crocodylus johnstoni).
An unusual attack by a small reef shark has resulted in a woman requiring surgery on her right arm. Turquoise Bay near Exmouth was closed after the woman was bitten. The 60-year-old was snorkelling with her partner at the popular beach in the Ningaloo area when the incident happened.
It might not be as big as the Great Barrier Reef, but Ningaloo is still one of the world's largest (and healthiest) fringing reefs. It's home to roughly 200 species of hard coral and 50 species of soft coral. The Great Barrier Reef has bigger and more diverse coral gardens, but Ningaloo's are just as spectacular.
There are thousands of unique species of wildlife to be found here and you can spot them in the rainforest, outback or the ocean. While most of them are harmless, there are a few you should stay away from, including crocodiles, marine stingers, snakes, spiders and Cassowary.
What is this? Crocodiles have been known to be as far south as the Mary River in Gympie. This is only about 167km from Brisbane and only 52km from the Great Sandy National Park. More astonishingly, this is a whopping 449km away from the northern points of Queensland where they are typically found.
Port Douglas is home to a large population of crocodiles.
Corals are fragile animals. Be careful not to touch, kick or stand on the corals you see in the water because this may damage or even kill them.
Can you breathe underwater with a snorkel? Unlike scuba diving equipment, snorkels do not allow you to breathe deep underwater. Instead, snorkelers must exchange air at the surface of the water through the breathing tube.
Do not touch corals, fish or turtles. The only thing you can touch safely is sand and rock and water (that means with your fins also). Read our snorkeling etiquette page for learning how to develop skills for taking a break in the water without having to stand. Don't use harmful sunscreen.
Blue-Ringed Octopus
It is also one of the most deadly marine animals in the world. The blue-ringed octopus, which grows to only about 5 to 8 inches, is armed with a venom powerful enough to kill 26 humans within a few minutes, and there is no anti-toxin for it.
A lot of beaches of the region are banned from swimming within, as the croc sightings are a bit more common than the outer ocean of the reef. However, all Great Barrier Reef tours keep a lookout for any crocodiles roaming nearby, with even small detections leading to all visitors leaving the water immediately.
Endangered Dugong in the Great Barrier Reef
The dugong, sometimes referred to as the elephant of the sea, is one of the most endangered animals in the Great Barrier Reef, Australia and the whole world. It's estimated that there's only 10,000 of these gentle giants left in the wild.
Predators of Crocodiles include humans, large felines, and birds of prey.
